Water level indicator having a remote and a local readout display |
摘要 |
A water level indicating apparatus (10) has an optical system (22) for establishing an optical signal indicative of water level which signal is split by a beam splitter (18) to transmit the majority of the optical signal to a fibre optic cable (16) and to reflect a part of the signal to a proximately located (13) glass diffuser (14). The cable (16) extends to a matte screen (12) at a remote location (11) to thus provide a remote (11) optical signal as well as local (13) optical signal indication of the water level.
